Sequence Letters Players sound out the letter on their cards, match it to the beginning sound of a picture on the gameboard, then place a chip there. Each card features a letter of the alphabet in upper and lower case. Coloured squares on the cards and gameboard help with faster recognition. When you have 4 of your chips in a row, you've got a sequence! Kids will have fun playing the great game of sequence while learning the letters of the alphabet. For 2-4 players. Recommended for ages 4-7.
